Обсуждение: postgres/php and windows

Any help would be appriecated

One thing to check is to make sure PHP was compiled with pgsql support. Provide more details and hopefully someone will be able to provide better help. Good luck!

The semicolon needs to be removed. ;extension=php_pgsql.dll If that does not solve it, give more specifics about the error. John DeSoi, Ph.D. http://pgedit.com/ Power Tools for PostgreSQL
I've run PHP and PostgreSQL for quite a while and never seen this problem before. I think it's new, but maybe I never paid attention to it before. I am frequently running out of connections to the database. Here's a snippet of my ps -ax 1882 ?? S 0:00.07 postgres: postgres cgssd_members [local] idle 1883 ?? S 0:00.09 postgres: postgres cgssd_members [local] idle 1884 ?? S 0:00.07 postgres: postgres cgssd_members [local] idle 1886 ?? S 0:00.14 postgres: postgres cgssd_members [local] idle 1887 ?? S 0:00.06 postgres: postgres cgssd_members [local] idle 500 std- S 0:01.14 /usr/local/bin/postmaster -D /usr/local/pgsql/data 501 std- S 0:00.02 postgres: stats buffer process 502 std- S 0:00.21 postgres: stats collector process As you can see, there are some idle connections that have come in from PHP on my web pages. I've never seen these before and eventually they build up and I get an error connecting from the PHP page to the database. I'm running Apache 1.3.33 on Darwin Kernal 7.9.0 (MacOS X 10.3.9) with PHP 4.3.6 and PostgreSQL 7.4.2. Ideas and suggestions are welcome.

You will have as many of these as you have apache processes. That's
what persistent connections means!
If you have MaxClients set to (e.g.) 150 in your Apache configuration,
and you actually get to something like that, then the default PostgreSQL
configuration of 100 clients simply won't be enough. You should
increase it to at leas 20-50 more than the MaxClients setting that
Apache has.
You'll be pleased to know that each extra PostgreSQL connection
typically uses less than each additional Apache connection (especially
when you're running PHP et al.) so if you find yourself running out of
RAM you will need to lower the MaxClients setting first.

Andrew McMillan.

In addition to error messages, what is your setup? What versions of PHP, Postgres and Web (Apache?) are you using? The configurations are different depending upon what you have installed. Also you should check the PHP manual: http://us3.php.net/manual/en/function.pg-connect.php. Cameron G.

Hello
First you will need to know wheter php is been setup corectly.
Paste this
<?php
phpinfo()
?>
into a textfile or you're favorite editor and save it as phpinfo.php or so in you're webroot (mydrive\Apache Group\ApacheX\htdocs)
then goto http://localhost/phpinfo.php
1) Configurationfile (php.ini) Path must piont to the place wher you stored you're php ini.
2) if you scroll down a bit you will find a block with "pgpsql" witchs means that you have postgres support enabled in php.
If not found that means you're php ini is not setup correctly
check www.php.net for more info on how to setup php.ini.

That's > what persistent connections means! You can end up with a *lot* more than apache's MaxClients if you open persistent connections with different connection paramaters... so keep that in mind if you're connecting to more than one database. You might look at pgpool. Never used it, but it comes up frequently as a solution to this... > > If you have MaxClients set to (e.g.) 150 in your Apache configuration, > and you actually get to something like that, then the default PostgreSQL > configuration of 100 clients simply won't be enough.

I would also suggest that others not check the links unless they are actively trying this install - at least until Dave is able to download the files. I will get the instructions up via a web page, but it proved to be difficult using geocities. Do fweel free to offer suggestions and point out errors of any kind.
